Taste is an important determinant of food consumption, and genetic variations in the sweet taste receptor TAS1R2 may contribute to why some of us consume more sugar than others.

The diverse tissue distribution of the TAS1R2 gene affects food intake beyond the detection of sweet taste on the tongue and palate. These tissues include the gastrointestinal tract, pancreas and hypothalamus, tissues known for regulating metabolic and energy homeostasis.

If you carry the AA-allele in this gene, then you are more likely to enjoy sweet tasting foods. You may benefit from adding in healthier 'sweet' foods than sugary carbohydrates. Try plan your snacks and balance your blood sugar throughout the day to help prevent unplanned snacking on sweet foods. When planning your daily food choices, consider your DRD2 genotype too.
